# The enveironment variable CGI_http_proxy and CGI_HTTP_PROXY is used
# instead of http_proxy and HTTP_PROXY in the CGI environment because
# HTTP_PROXY can be set by Proxy: header sent by a CGI client.
# Note that capitalized variables (HTTP_PROXY, FTP_PROXY, NO_PROXY, etc.)
# are examined too.
#
# But http_proxy and HTTP_PROXY is treated specially under CGI environment.
# It's because HTTP_PROXY may be set by Proxy: header.
# So HTTP_PROXY is not used.
# http_proxy is not used too if the variable is case insentitive.
# CGI_HTTP_PROXY can be used instead.
